I remember replacing the strap on my Classic but it was a lot of years ago. And it’s when I found the Bass Cat build slip (a very dirty one as it had been tucked in there 4-5 years) tucked up under the step over of the winch! Anyway, I remember removing just the one bolt ( I do remember it wasn’t easy) that beginning of strap is attached to. I don’t recall how it was attached exactly but I think there is a sheath the bolt goes through and strap attaches to that somehow. This was on a 07 Classic trailer, don’t know if same set up used for later models.
